SPECIFICATION forming part of Letters Patent No. 710,962, dated'OCtober14, 1902.

Application iiled December 21, 1901. Serial No. 86,793. (No model.)

To f/,ZZ 707mm, t may con/ecrit:

Be it known that we, RUDOLPH FLEISCHER and MATTHIAS REITHMAIR, subjectsof the Emperor of Germany, residing at Minden, in the Kingdom ofPrussia, Germany, have invented certain new and useful Improvements inPneumatic Tires; and We declare the following to be afull, clear, andexact description of the invention.

The object of our present invention is a pneumatic tire consisting ofanumber of separate air-tubes. It has the advantage over all hithertoknown constructions that instead of having many separate air-cells ithas a few air-tubes Which can be taken in and out of the tire-case bymeans of openings in the same which can be opened or closed at will.

The invention is described in the accompanying drawings.

Figures l and 2 show a portion of the tire with open and closed ap; Fig.3, a section in the line A B of Fig. 2; Fig. 4, a longitudinal sectionthrough a portion of the pneumatic tube; Fig. 5, an air-tube.

The construction is as follows: A number of flaps b are cut in thetire-case a, one for each air-tube, and separated by distancescorresponding to the number of tubes. Through the openings c herebyformed the air-tubes CZ are introduced before being pumped up. Oppositethe openings c in the case are openingsfin the felly c to admittheair-'valves g. The air-tubes cl are provided With a lace h, which isattached to a band t, fixed to the tube. The lace serves to introducethe airtube into the case before pumping it up. By

this operation the lace h is introduced, and the next flap b is openedand Ithe lace drawn out, whereby the airtube el` is drawn in. Then thevalve g is set in the openingf in the felly e. Finally, the lace is alsopressed into the space within the case. The fiaps b are closed by meansof a piece of material 7c, the longitudinal edges Z of which arethickened. This is laid over the closed flap b before the tube ispumped` up, so that the thickened edges come Within the rims of thefelly c. /Vhen the tube is pumped up, the case is consequently stretchedout, with the result that the thickened edges lare pressed Very stronglyagainst the rims and the aps b thereby kept lirmly closed.

Havingnow described our invention, what we claim is- Y A pneumatic lireconsisting of separate airtubes and distinguished from all otherpneumatic tires by havingva case a in which aps b' are cut at distancescorresponding to the number of tubes, through the Hap-openings cair-tubes d can be introduced by means of laces h into' the space Withinthe case, Which is closed by a piece of material 7c Which is laid overthe flap b and the thick edges lof which are grasped by the rims of thefelly e.

In Witness whereof We have hereunto set ourhands in presence of twoWitnesses.
